"Changing to renewable diesel allowed us to immediately reduce emissions from our entire fleet, rather than making a series of small improvements as we replace vehicles one at a time."

WestCAT has also observed significantly cleaner operation of their bus engines and a significant reduction in the maintenance needed for the emissions equipment and internal engine components.

Neste US sales vice president Jeremy Baines said: "Neste is happy to have a progressive transit agency like WestCAT join the ranks of other front-runners in the quest towards more sustainable solutions.

"By making the switch to Neste MY Renewable Diesel, they are committing to reducing emissions without compromising fleet performance."

WestCAT serves the cities of Pinole and Hercules, and unincorporated communities along the eastern edge of San Francisco Bay, operating a network of 14 fixed routes. WestCAT operates 365 days a year, serving more than 65,000 residents within a 20 square mile service area, and carries more than 1.3 million passengers annually.

Neste MY Renewable Diesel is a low-carbon fuel, produced from 100% renewable and sustainable raw materials. This innovative fuel cuts greenhouse gas emissions by up to 80% and significantly reduces engine-out emissions, all while enhancing fleet performance.

Neste MY Renewable Diesel is a drop-in alternative to petroleum diesel and is distributed via the same fuel infrastructure.
